To all whom it may concern Be it known that 1,} DUDLEY SMITH, a citizen of the United States ofAmerica, residing at Benton, in the; county of Frank lin and State of Illinois, :have invented new and useful Improvements in Excavating Attachments for Motor-Vehicles, of which the following is a specification;

This invention relatesto improvements in excavators or ditching and grading ma:

chines and. has particular iapplicationito excavating and conveying; attachments for self-propelled vehicles.

In carrying out this invention, it is my purpose to provide an excavating and con veying attachment which; may be attached to and detached from a self-propelledvehicle, such as a tractionengine to enable such engine to be utilized for excavating purposes.

Furthermore, Iaim to provide an attachment of the characterdescribed wherebya self-propelled vehicle, as; a traction; engine, may be convertedinto aditchingand grading machine, the excavating and conveying apparatus being detachably mounted :upon the traction engineand; driven therefrom to effect the excavating operation r and enable the discharge of the material excavated into a suitable carrier, such as awagon or :the like.

Another object of the presentfinventiom is the provision ofan excavatingand conveys traction engine equipped with the present;

ing device which shall embrace the desired features of simplicity, efficiency and durability coupled with cheapnessof cost and manufacture and which may be attached to any well known or preferred form of self-: propelled vehicle or traction engine without affecting the structure of such engine 0 11ecessitating an elaborate attaching ;1meohathe invention consists in "the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims. I

in the excavating operation, from the excaw vator and carry the same away from such excavatoriand deliver such material to a;

wagon or other vehiclea The excavator and conveyer are supported upon an attaching frame capable of attachment to and detach: mentfrom aself-propelled vehicle as a traction on ine, the excavator being drawn :by

the vehlcle andithe elevating conveyer being driven from such vehicle in the grading or The opposite ends of the=excavator and the conveyer are adjustditching operation.

able independently of each other and the excavator is adjustable independently of the.

conveyer; to facilitate the excavating operas tion, the adjustment; of the excavator and. conveyer being preferably efiected manually and by an operator upon the vehicle.

1 Referring; now to the accompanying drawings in detail, Aindicates a self-propelled vehicle shown in the present instance to be a tractionengine equipped with a horizontal boiler 1, steering wheels 2 and the a traction wheels3, an engine 4.- being mounted upon; the boiler and ;in communication with the steam; dome thereof and having: driving connectionswith the traction wheels I 3, such connections in the presentinstance consisting of a pinion 5 keyed to the crank shaft of the engine and meshing with a gear wheel 6 journaled upon a stub shaft supported within suitable brackets upon the boiler andzmeshing with a gear wheel 7 also secured to a suitable stub shaft to which lat ter is keyed a pinionmeshing with a gear;

wheel 9 upon the rear axle 10of the traction wheels. I

Surrounding the boiler 1 preferably immediately in advance of the fire box thereof are a pair of spaced attaching rings 11,;11

each consisting of two sections 12 and 13 provided at theirlmeeting ends with out iturned lugs 14 formed with apertures a1in-- ing with theap ertures in the :adjacentlug and adapted to receive fastemng bolts The lugs 14, 14: at the opposite extremitles,

This shaft 55, is arranged longitudinally of the fire box of the engine as shown and at its free end is equipped with a beveled pinion 56 meshing with a similar gear 57 bolted or otherwise secured to a peripheral toothed gear 58 driven from a pinion 59 keyed upon one extremity of a shaft 60 and receiving power from the engine 4:.

In practising the present invention, the steering wheels 2 of the engine are manipulated for steering purposes from the cab of the vehicle as usual and the mechanism thereof is constructed inisuch manner as to operate freely irrespective of the attaching of the excavator and conveyer to the vehicle. This steeringmechanism preferably consists of an elongated shaft 60" designed to be passed through the attachingflange 16 on the sections 12 of the rings 11 and terminating at one extremity within the cab of the engine a and equipped at such extremity with a steering wheel of any usual orpreferred construction, while the opposite end of such shaft is journaled in a bracket 62 and has keyed thereto a beveled piniony63 meshing with a similar pinion 64: keyed upon one end of a shaft 65 extending :beneath the boiler and at an angle to the shaft 61 and having its gear carryingextremity journaled in:the bracket 62. Surrounding: the boiler in advance of the rings 11, 11, isa fastening ring 66 formed of two sections 67 and 68 each having its opposite extremity outturnecl to provide coupling lugs alining witlrthe lugs in the adjacent section and apertured to receive fastening bolts or the like: Depending from the lower sectionof the rings 66 beneath the boiler, are transversely curved spacedparallel supporting strips 69 and between such strips at the lower extremities thereof is journaled a shaft? 70 equipped at one end beyond the strips with a worm gear 71 meshing with a worm72 upon the end of the shaft 65, while keyed tothe shaft 70intermediate the strips 69 is a toothed pinion 73 meshing with a crown gear segment 74; fastened at its opposite extremities Ito the steeringaxle 28 and held in engagementiwith the toothed pinion 73 by meansvofi rollers 7 5 journaled in the free extremities of the strips 69 beneath the shaft 70. These rollers 7 5 are preferably journaled in arcuate shaped slots 76 so as tomaintain the crown gear segment in engagement with the toothed pinion73 at all times irrespective of the osition of :steeringwheels of the vehicle, moident to suchiwheelsengaging or contacting with irregularities in the roadway intheir path of travel. Thus, upon manipulating the steering wheel of the shaft 61, motion will be imparted to the shaft 65 thence, by way of :the worm 72:a11d worm gear 71, to theshaft 70 to actuate the pinion 73 and: crown gear segment 74 to throw the steering wheels 1n;the desired direction to change the path of travel of the vehicle. A platform ,7 7 is fastened to the vehicle in proximity tothe standard 31 to accommodate an operator.

From the foregoing description taken in connection with the accompanying drawings, theiconstrlution, mode of operation and manner of employing my invention will be readily understood by those-skilled in the art to which the invention 'appertains, and while I have herein shown and described one particular form of my invention, it is to be understood that I do not limit or confine myself to the exact details of construction herein described and delineated, as

modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.
